3 Tender specification Attenuator: Zehnder ComfoWell attenuator CW-S 220. Compact rectangular attenuator with high-efficiency special sound attenuation pack and low pressure losses. The attenuator can be used on its own or in combination with any add-on from the ComfoWell system. It is connected to all add-ons with a folded joint and clamping rail to create an airtight seal. The attenuation element can be removed for inspection and cleaning. The attenuator is mounted on a wall or ceiling with height-adjustable mounting brackets. Mounting accessories are supplied with the unit. Technical specifications: Insertion loss: 11.1 db / 250 Hz Housing: galvanised sheet steel Attenuation element: special foam with hygienic coating Dimensions: length: 500 mm; depth: 220 mm; height: mm Manifold box: Zehnder ComfoWell manifold box CW-D 220. Compact soundabsorbing manifold box with closed-cell, attenuating inner lining, fits mounting plate for ComfoTube 4 x 75 or 4 x 90 ventilation tubes. The mounting plate connection can be moved from the front to the side. The manifold box can be used on its own or in combination with any add-on. It is connected to all add-ons with a folded joint and clamping rail to create an airtight seal. The manifold box features an access panel for easy cleaning and adjustment of the ComfoTube ventilation tubes. Mounting accessories are supplied with the unit. Material: galvanised sheet steel Dimensions: length: mm; width: 220 mm; height: mm Mounting plate: Zehnder ComfoWell mounting plate CW-M x 75 or 90 for connecting 4x Zehnder ComfoTube 75 or 90 flexible ducts. Supplied with guard and clamping rails. Mounting plate can also be used for mounting in concrete. End plate: Zehnder ComfoWell end plate CW-P 220 DN125 (with central support) for connecting the ComfoWell attenuator and distribution system to a DN125 round duct. A special end plate is available for the CA 180. Clamping rails included. Mounting set: A special mounting set is available for the Zehnder ComfoWell 220 attenuator and distribution system for direct mounting on the ComfoAir 160 ventilation unit. The mounting set includes all the necessary accessories (screws, brackets and mounting brackets). Spacer frame: Zehnder ComfoWell spacer frame CW-DF 220 to compensate for uneven surfaces when components and mounting plate (concreted in place) are at 90. Spacer frame includes the necessary mounting accessories. Filter: Filter for mounting in filter housing CW-F 220. Available filter classes include F7 (pollen filter), F9 (fine dust filter) and an active carbon filter for odour neutralisation. Filter housing: Zehnder ComfoWell filter housing CW-F 220. Compact filter housing for mounting in supply line, to accommodate pollen filter F7 or active carbon filter element. Filter elements are not supplied with the unit. The manifold box can be used on its own or in combination with any add-on from the ComfoWell system. It is connected to all add-ons with a folded joint and clamping rail to create an airtight seal. It is mounted with adjustable mounting brackets; mounting accessories are included. Material: galvanised sheet steel Dimensions: length: 300 mm; width: 220 mm; height: mm 3
